Remarks (public):Characteristic species but under the microscope very close to e.g. S. muscicola, alboluteum, and dennisii. The former species is reported to have the same smell of vanilla in the living state (T. Nathorst-Windahl in Lund.& Nannf. Fung. exs.suec. n. 1415 a). Fries described it as "inodorum". The smell of vanilla is only perceptible from fresh, living material.

Description:Sistotrema confluens Fr., - Syst. mycol. 1 p. 426, 1821.
Fruitbody generally pileate but may sometimes be resupinate on underside of leaves etc., mostly 1-2 cm wide, more or less flabellate and often radially incised, with a lateral, seldom central, tapering stipe with blackish base; pi-lei as a rule concrescent with several stipes; the whole fungus in the living state white or pale cream-coloured, but with age or when bruised turning yellow or brownish, soft in the living state, young fruitbodies very brittle when dried, old ones more tough; upperside of the fruitbody smooth or irregularly-concentrically wavy or wrinkled, under the lens appressed tomentose; hymenophore varying from reticulate pores or flattened, irpicoid plates, sometimes lamelloid, to 1-2 mm long cylindrical spines; smell distinct and characteristic, described by some people as vanilla, by others as «disagreeable».
Hyphal system monomitic; hyphae thin-walled, 2-3 µm wide, with many oil-drops; hyphal inflations (to 5 or 7 µm) sometimes present; hyphal direction mainly parallel in the trama of the stipe, pileus and hymenophore.
Cystidia none.
Basidia when young subglobose, when mature urniform, (12-)14-18(-22) x 3.5-4.5(-6) µm with 6-8 sterigmata (a few with 4 sterigmata seen) and basal clamp.
Spores 4.5-6 x 2-2.5 µm, narrowly ellipsoid-suballantoid, smooth, thin-walled.
Habitat. On the ground among mosses and fallen leaves and other litter in deciduous or coniferous forests, less often in open fields.
Distribution. Found in S. Scandinavia to the Swedish province of Dalarna and S. Finland in the north, mostly rare but locally, especially on fertile soil more frequent, e.g. in Uppland (Sweden).
